摘　　要：采用减压凝固密度试样法和电阻法,对不同程度精炼除气和变质下的ZL101合金进行夹杂物检测,分析含气量、变质元素锶与夹杂物之间的关系。结果表明,精炼时间越长,含气量越低,夹杂物尺寸越小,数量越少;变质过程中,随着锶的含量增加,含气量增大,夹杂物尺寸增大,数量增多。In this paper,the vacuum solidification density sample method and the resistance method are used to detect the inclusions of the ZL101 alloy under different degrees of refined degassing and modification,and analyze the gas content,the relationship between the modification element strontiumand inclusions.The results show that the longer the refining time,the lower the gas content,the smaller the size of inclusions,and the smaller the number.During the modification process,as the content of strontium increases,the gas content increases,the size of the inclusions increases,and the number increases.

关 键 词：铝合金 变质 含气量 夹杂物
